It seems like the other replies are missing the point of your question in the context it is asked. Every country within the EU has its own guidelines for enforcing the GDPR, and a regulator appointed to oversee privacy cases. So if you hold infringing data in a German AWS region, it is subject to the German regulator's authority. In a weird kind of statistical anomaly among all other EU countries except Luxembourg, Ireland's regulator has never issued any fines for GDPR violations, and seems to be twiddling their thumbs on incoming cases.

What the other commenter is proposing is a single regulator for the entire EU. Sure, that may be a solution, but it's not the law that was agreed upon.
